I've had the card a couple months and am just started playing with overclocking it. Right now I have it at 1150/1450 stable but each time I bump it to 1500 memory clock it crashes. So from here do I need to increase my voltage, the VDDC option in Trixx? So far I've been running tests with the Heaven Benchmark on custom settings, Quality: High Tessellation: Normal AA: x4 1920 x 1080 DX11 This is my first time toying with a gpu so I just want to be sure I don't fry something haha. Temps have sat around mid 60's only jumping up to 66+ now that I've bumped by memory up to 1450. I'm curious as to what would be better to have raise higher now, the memory to that 1500 that I read of many people reaching or the core clock to 1200+.
